Description

Technical Field

[0001] The utility model relates to the technical field of measuring devices, in particular to an engineering measuring ruler. Background Art

[0002] The existing engineering measuring rulers on the market can not only measure distances, but also determine whether the building surface is flat. They can also be used as scrapers, making them an indispensable tool on construction sites.

[0003] However, the existing measuring ruler cannot measure the gap distance between the building surface and the measuring ruler, and it is also impossible to measure the uneven data of the building surface. Other personnel are often required to use another ruler to lean on the measuring ruler to measure the gap at a single point. The operation is very troublesome and generally requires two people to cooperate. In addition, the flatness of the building surface cannot be intuitively checked during the measurement process. Secondly, when measuring some top surfaces or positions where readings cannot be taken, there is no way to measure the gap, and reading is also a problem.

[0004] Secondly, the existing product structure generally adopts a flipping method, and the flipping point is an arc. When the engineering ruler is unfolded into a straight line, a herringbone-shaped depression will appear above and below the rotation point. The building surface measured at this depressed position is inaccurate, and this point cannot be measured. In addition, engineering personnel know that in addition to the measurement effect, the engineering ruler can also be used as a scraper on the construction site to scrape the mortar material flat. Although this structure has achieved adjustment, it cannot achieve this function. At the same time, it is impossible to accurately judge whether the engineering ruler is 90 degrees or parallel after flipping. Therefore, we proposed an engineering measurement ruler.

[0016] The utility model provides an engineering measuring ruler, which has the following beneficial effects:

[0017] 1. The engineering measuring ruler is used in conjunction with a gap measuring ruler, a mounting rod, an extrusion block, a push spring and a traction wire. When the flatness of a building surface needs to be measured, the engineering measuring ruler is placed against the building surface. If the building surface is uneven, and the gap between the building surface and the plane, that is, the engineering measuring ruler, needs to be measured, the drive motor is used to drive the roller to rotate, and then the traction wire is released. At this time, the push spring will push the gap measuring ruler to move. When the end of a single gap measuring ruler contacts the building surface, it will stop moving, while the other gap measuring rulers will keep moving and contact the building surface. At this time, the staff can directly read the gap measurement The gap can be known by reading the scale on the ruler or reading the scale pointed by the corresponding triangular pointing block. When it is impossible to read directly or inconvenient to read during operation, the installation rod is pushed to move by rotating the screw rod, so that one end of the extrusion block contacts and squeezes the side of the gap measuring ruler, and then the gap measuring ruler is fixed. After fixation, the engineering measuring ruler can be taken down to facilitate reading and recording. This structure can help staff to judge the surface data of the building surface intuitively and conveniently, can measure multiple points at one time, and is easy to operate. One person can operate it, which improves the convenience of using the engineering measuring ruler.

[0018] 2. The engineering measuring ruler is used in conjunction with the connecting block through the positioning block. By pushing the push block to the left, the supporting spring is compressed to move the connecting block toward the inner cavity of the installation slot. Then, the other engineering measuring ruler is rotated to make the two engineering measuring rulers contact and fit together at one end. The push block is slowly released. At this time, the supporting spring pushes the connecting block to move, so that part of one end of the connecting block is inserted into the inner cavity of the connecting slot and fits with the inner wall of the connecting slot. The iron block at the end of the connecting block is attracted by the magnet. Since the surface of the connecting block fits with the installation slot and the inner wall of the connecting slot, the two engineering measuring rulers are aligned. The connection is limited so that the two engineering measuring rulers are parallel to each other due to the influence of the connecting block. When the two engineering measuring rulers need to be in an L shape, the push block is still pushed to retract the connecting block into the inner cavity of the installation groove. When the connecting block is separated from the inner cavity of the connecting groove, the two engineering measuring rulers rotate around the hinge point. At this time, the push block is released, and then the positioning block is inserted into the inner cavity of the connecting groove after passing through the inner cavity of the connecting block and adsorbed by the magnet. At this time, the two engineering measuring rulers are at ninety degrees and can be used to measure the top and ground of the building. It is convenient to adjust and has high stability and will not change during the measurement process. BRIEF DESCRIPTION OF THE DRAWINGS

The mounting rod 8 is slidably mounted inside the engineering measuring ruler 1 , and the mounting rod 8 is located on one side of the gap measuring ruler 4 . The surface of the mounting rod 8 is connected to the extrusion block 36 .

[0032] A driving motor 20 is fixedly connected inside the engineering measuring ruler 1, and the output shaft of the driving motor 20 is connected to the winding roller 7. The winding roller 7 is located inside the engineering measuring ruler 1. A T-shaped avoidance groove 33 is provided on the surface of the engineering measuring ruler 1 and in front of the gap measuring ruler 4.

[0033] The number of extrusion blocks 36 matches the number of gap measuring rulers 4. A rubber pad is connected to one end of the extrusion block 36. An anti-slip pattern is provided on one side of the gap measuring ruler 4. A connecting column 34 is connected to the front of the gap measuring ruler 4. The connecting column 34 passes through the T-shaped avoidance groove 33 and is connected to a triangular pointing block 39. The front of the triangular pointing block 39 is parallel to the front of the engineering measuring ruler 1.

[0034] One end of one of the engineering measuring rulers 1 is provided with a mounting groove 18, one end of the inner cavity of the mounting groove 18 is fixedly connected to a support spring 10, the inner cavity of the mounting groove 18 is slidably connected to a connecting block 11, the connecting block 11 is fixedly connected to the support spring 10, one end of the inner cavity of the connecting block 11 is movably sleeved with a positioning block 12, the positioning block 12 and one end of the connecting block 11 are both provided with an iron block, one end of the other engineering measuring ruler 1 is provided with a connecting groove 14, the bottom of the inner cavity of the connecting groove 14 is installed with a magnet 15, one end of the positioning block 12 is plugged into the inner cavity of the magnet 15, a push block 17 is connected to the surface of the connecting block 11, the push block 17 passes through the engineering measuring ruler 1 and extends to the outside of the engineering measuring ruler 1.

[0035] The two engineering measuring rulers 1 are hinged, and an angle measuring disk 16 is installed on both engineering measuring rulers 1. A pointer is rotatably connected inside the angle measuring disk 16, and a level is installed on the engineering measuring ruler 1.

[0036] One end of one of the engineering measuring rulers 1 is internally threaded with an adjusting screw 3, one end of the adjusting screw 3 is rotatably connected to the mounting rod 8, one of the engineering measuring rulers 1 is internally provided with a battery, and the battery is electrically connected to the driving motor 20, and a control switch is installed on the front of the engineering measuring ruler 1.

[0037] A distance scale is provided on the front of the engineering measuring ruler 1 and on one side and above the triangular pointing block 39 , and a distance scale is provided on the surface of the gap measuring ruler 4 .

[0038] A line receiving cavity 29 is provided at one end of one of the engineering measuring rulers 1. The line receiving cavity 29 is used to receive the curved line when the two engineering measuring rulers 1 are connected.

[0039] In summary, when the engineering measuring ruler is used to measure the building surface, the positioning block 12 is first pulled out from the connecting block 11 and the inner cavity of the connecting groove 14, and then the positioning block 12 is removed, and the push block 17 is pushed to the left by the finger, thereby compressing the support spring 10 to make the connecting block 11 move toward the inner cavity of the installation groove 18, and then the other engineering measuring ruler 1 is rotated to make the ends of the two engineering measuring rulers 1 close to each other contact and fit together, and the push block 17 is slowly released. At this time, the support spring 10 pushes the connecting block 11 to move, thereby partially inserting one end of the connecting block 11 into the inner cavity of the connecting groove 14 and fitting with the inner wall of the connecting groove 14, and the iron block at the end of the connecting block 11 is adsorbed by the magnet 15. Since the surface of the connecting block 11 fits with the inner wall of the installation groove 18 and the connecting groove 14, when the connecting block 11 is inserted into the inner cavity of the installation groove 18 and the connecting groove 14, there is no gap between the surface of the connecting block 11 and the inner wall of the installation groove 18 and the connecting groove 14, resulting in the inability of the two engineering measuring rulers 1 to rotate.

[0040] Then, the two engineering measuring rulers 1 are connected and limited so that the two engineering measuring rulers 1 are parallel to each other under the influence of the connecting block 11.

[0041] By placing one side of the engineering measuring ruler 1 directly against the building surface, the distance and size can be measured and read through the scale on the engineering measuring ruler 1.

[0042] When it is necessary to make the two engineering measuring rulers 1 into an L shape, the push block 17 is still pushed to retract the connecting block 11 into the inner cavity of the installation groove 18. When the connecting block 11 is separated from the inner cavity of the connecting groove 14, the two engineering measuring rulers 1 rotate around the hinge point. At this time, the push block 17 is released. At this time, the connecting block 11 is pushed to the limit position under the action of the supporting spring 10, and the inner cavity hole of the connecting block 11 is parallel to one of the engineering measuring rulers 1. It can be used as a scraper for leveling the wall without dead angles.

[0043] Then, after the positioning block 12 passes through the inner cavity of the connecting block 11, the positioning block 12 is parallel to the side wall of one of the engineering measuring rulers 1. At this time, the angle of the other engineering measuring ruler 1 is unknown, and the other engineering measuring ruler 1 needs to be rotated so that one end of the positioning block 12 can be inserted into the inner cavity of the connecting groove 14, and the outer wall of the positioning block 12 is also in contact with the connecting groove 14 and the inner wall of the connecting block 11. Therefore, as long as the positioning block 12 can be inserted into the inner wall of the connecting groove 14, the two engineering measuring rulers 1 are at a 90-degree state. When the positioning block 12 is inserted into the inner cavity of the connecting groove 14 and is adsorbed by the magnet 15, the pull ring at the top of the positioning block 12 is just against the connecting block 11. As long as the two engineering measuring rulers 1 are not at a 90-degree angle, the positioning block 12 cannot be inserted into the inner wall of the connecting groove 14. Therefore, the connecting block 11 is at a 90-degree angle with the positioning block 12. After the positioning block 12 is connected to the inner cavity of the groove 14, it is in a vertical state with the other engineering measuring ruler. Therefore, the two engineering measuring rulers 1 are at a 90-degree angle, which can be used to measure the top surface and the ground of the building.

[0044] When measuring the angle of a building surface, one of the engineering measuring rulers 1 is placed against the building surface and fits with the building surface. At this time, the angle of the building surface can be measured by reading the value pointed by the pointer in the angle measuring disk 16 on the other engineering measuring ruler 1.

[0045] When it is necessary to measure the gap between the building surface and the plane, that is, the engineering measurement ruler 1, the driving motor 20 is controlled to be turned on, and the driving motor 20 is used to drive the winding roller 7 to rotate, and then the traction wire 5 is released. At this time, the pushing spring 9 will push the gap measuring ruler 4 to move. When the end of a single gap measuring ruler 4 contacts the building surface, it will stop moving, while the other gap measuring rulers 4 will continue to move and contact the building surface. At this time, the staff can directly read the scale on the gap measuring ruler 4 or read the scale pointed by the corresponding triangular pointing block 39 to know the gap. When it is impossible to read directly or it is inconvenient to read during operation, the adjusting screw 3 is rotated at this time, and the adjusting screw 3 is used to push one of the mounting rods 8 to move. At this time, the two mounting rods 8 are in a straight line, which pushes the other mounting rod 8 to move, so that one end of the extrusion block 36 contacts the side of the gap measuring ruler 4 and squeezes the side of the gap measuring ruler 4, thereby fixing the gap measuring ruler 4. After fixing, the engineering measurement ruler 1 can be taken down at this time to facilitate reading and recording.

[0046] After reading the value or taking a photo to record it, rotate the adjustment screw 3 in the opposite direction to reset it. At this time, all the gap measuring rulers 4 will extend to the limit state under the elastic force of the pushing spring 9, and then control the driving motor 20 to rotate in the opposite direction, and then reel in one end of the traction wire 5 through the winding roller 7, and then pull the traction wire 5 to pull the gap measuring ruler 4 into the inner cavity of the mounting hole 37, and at the same time compress the pushing spring 9. After all the gap measuring rulers 4 are pulled into the inner cavity of the mounting hole 37, turn off the driving motor 20 for easy storage and reset. When the entire structure is not in use, the engineering measuring ruler 1 can be used as a traditional measuring ruler.

[0047] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
